Sneak, here is a picture of the unit we purchased, just scroll down to the HS322 Unit and that is the one we bought. As I stated above we got it for a much better price than shown here by doing some comparative shopping. I wish I could remember where I bought it from but you know how it is when you get old(er).
I've only used it for a few outdoor venues, and it was fine for those, however if it was a LARGE outdoor event I'm not quite sure how far it would extend out.
We have used it indoors with great success. In fact, at our last SAM show we do annually the theatre's sound system did not have the wireless mic system as promisesd Luckily, we never leave anything to chance and had thrown our system into the back of the SUV just as a precaution--- good thing too! Everyone in the show used ours and it worked like a gem. If you watched my daughter's video on her website you are hearing her speaker system so you can judge the clarity for yourself.
Hope this info helps!
